Profile

Tyre profile height. This parameter is specified as a percentage of the profile width (see above).

The higher the profile, the better the motorcycle can carry heavy weight and increased loads when driving on rough roads and the lower its stability at high speeds. Therefore, for high-speed driving on high-quality flat tracks, hard-surface motorcycle tracks, etc. use ultra-low-profile rubber, with a profile height of up to 60%. For most east european roads, given their overall quality, rather low-profile tyres are recommended — 60 — 80%. And tyres with a profile height of more than 80% should be chosen when the key points are not speed, but cross-country ability and resistance to stress.

Now on the market there are tyres with the following profile height: 40%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 90%, 100%.

Rim diameter

Tyre inner diameter. This value must correspond to the rim diameter of the wheel on which the rubber is planned to be installed — otherwise the installation will not be possible. You can find out the size of the wheel from the documentation for the motorcycle, from the markings on it, according to the characteristics of the old rubber (if the tyres are bought for replacement), in extreme cases, you can measure the diameter of the disk yourself.

Now on the market tyres with the following diameters: 10", 11", 12", 13", 14", 15", 16", 17", 18", 19", 21".

Load index

The load index indicates the maximum weight load that the tyre can safely carry in normal operation. To shorten the marking, this parameter is denoted by a two-digit number; you can translate this designation into a specific weight in kilograms using special tables.

This value must not be exceeded — otherwise the tyre may burst at any time due to off-design loads. At the same time, when choosing motor tyres for this parameter, it is worth remembering that the load is distributed unevenly between the front and rear wheels. However, the task is facilitated by the fact that motorcycle manufacturers can indicate the minimum or recommended load indices for the front and rear axles in the documentation for their equipment.
